The mutex to be destroyed.
This routine destroys the specified mutex by uninitializing it, and should be called when a mutex object is no longer referenced. After this routine is called, DECthreads may reclaim internal storage used by the specified mutex.
It is safe to destroy an initialized mutex that is unlocked. However, it is illegal to destroy a locked mutex.
The results of this routine are unpredictable if the mutex object specified in the mutex argument does not currently exist, or is not initialized.
If an error condition occurs, this routine returns an integer value indicating the type of error. Possible return values are as follows: Successful completion. An attempt was made to destroy the object referenced by mutex while it is locked or referenced. The value specified for mutex is invalid.
Functions: pthread_mutex_init(3), pthread_mutex_lock(3), pthread_mutex_trylock(3), pthread_mutex_unlock(3)
